Burning wire combustion tester

Burning wire combustion testerProduct Introduction

This testing machine heats a specified material (Ni80/Cr20) and shape of electric heating wire (Φ 4 mm nickel chromium wire) with high current to the test temperature (550 ℃~960 ℃) for 1mi, and then burns the test sample vertically at the specified pressure (0.95 ± 0.1N) for 30 seconds. The ignition hazard of the finished electrical and electronic equipment is determined based on whether the test sample and the substrate ignite or hold on for a certain period of time; The determination of ignition properties, ignition temperature (GWIT), flammability and flammability index (GWFI) of solid insulation materials and other solid combustible materials is also applicable to the insulation materials, engineering plastics or other solid combustible material industries.

Applicable standard

IEC60695 UL746A IEC829 DIN695 VDE0471

Features

Adopting a single-chip microcomputer and touch screen control, a high-precision temperature gauge independent electronic control system solves the problem of the inability of PLC system to achieve actual conversion accuracy between digital and analog, while also improving resistance. Using microcomputer control is more accurate.

Start, timing, exhaust, lighting, and heating are all implemented on the touch screen; After the completion of a set of experiments, the device automatically pops up the save button, and only the save name needs to be edited; All saved data can be queried in historical data

Seven inch color touch screen

Intelligent 7mm limit adjustment

Fixture adapts to various shapes and sizes of specimens

X. Z-direction free movement, convenient for customers to locate samples

Adopting one click operation, the entire testing process is completed with one button during the experiment, without the need to switch between complex buttons

The sample car adopts a fully enclosed structure and will not overturn

Equipped with a flame height gauge for easy observation of flame height
